If you downloaded any forms from a financial institution they may have a 1099-INT included as a summary form. Dividends should only be reported on 1099-DIV... although sometimes interest from a Credit Union will be titled as Dividends. For tax purposes dividend payments on deposit or share accounts in credit unions must be reported as interest income, according to the IRS.
In order to see where the interest was entered you can go to the forms mode in TurboTax and view your 1099-INT statements. This will indicate where the interest is coming from.
To switch to Forms Mode, open your return and click the Forms icon in the upper-right corner of your screen (or choose Forms from the View menu at top).
The 1040 Worksheet will display and all the forms in your return will be listed on the left side. Simply select a form to open it.
To switch back to the interview, click the Step-by-Step icon in the upper right corner, or choose it from the View menu.
